luz/grim Nrrn TATES HERMAN EPPRECHT, OF NEW YORK, N. Y.

GAS-BURNER.

SPOIFICATON forming part of Letters Patent No. 520,521, dated May 29, 1894.

Application led May 22, 1893. Serial No. 475.141. (No model.)

T @ZZ whom, it may concern:

Be it known that I, HERMAN EPPREOHT, of the city, county, and State ofNew York, have invented certain new and useful Improvements inGas-Burners, of which the following, with the accompanying drawings, isa specification.

My invention relates to improved devices for attenuating the force orpressure of the gas, and to a device for forming a continuous flame ofreduced size and other improvements hereinafter more fully described andset forth in the claim.

In the drawings, Figure 1 is a partly sectional view of the invention.Fig. 2 is a secr tional view on line X. X. of Fig. l. Figs. 3

and 4 are detail views. Figs. 5 and 6 are views showing flame protectorand means for operating it.

A is the tip or burner.

B is an adjustabletip holder having ascrew extension B2. Y

C is a milled thumb-nut on the tip holder.

D is a lock nut.

E is the upper semi-globular shell having a milled rim E2, and screwthreaded on the inside.

Fis the lower semi-globular shell, also screw threaded, to tit into theupper shell, also containing the seat for the key G, and the nut K forattaching it to the main gas pipe.

G is the key of the usual form but having a circumferential groove P2 inline with the gas conduit P. t

G2 is a spur on key.

G3 is a stop on the lower shell.

H is a deiiector or gas check having a flange H2, and secured between,and separating the upper shells E3 and F2, and having a downwardlyextending hood or cap P4 covering and overlapping the upwardlyprojecting gas conduit P2.

H2 is the upper concaved end of the deilector.

I, I2, I4, I5 are gas passages in the delector.

I3 is a downwardly projecting gas passage in the deiiector.

l6 isthe end of the gas passages l, I2 leading into the chamber E2.

J is the usual nut securing the key in position.

K is the nut or screw for attaching the device to the main gas pipe.

L is a globe or flame protector.

M is a connecting rod.

N is a lever.

O, O2 are chains for operating the lever N.

P is the gas conduit in the key G.

P2 is a circumferential groove cut in the w part P3 and out into thelower chamber F2, striking the bottom of the chamber F2, againdiminishing its pressure by arresting its course; then it passes intothe passages or openings I, I2 in the defiector, taking an upwarddirection, then goes in a horizontal direction through the passages I4,I5, then downwardly through the passage l2 and out through the slit l6into the upper chamber E2, then out between the concave upper end of thedeflector H, and the end of the screw B2 and out to thetip A to beconsumed. It Will be readily perceived that the gas having passedthrough so circuitous a series of passages from pipe K to tip A andhaving its course arrested and deflected so many times before beingconsumed must have lost materially its force of pressure and that itisalso heated by the heat of the tip being conducted to the parts belowit, the result is a steady llame.

When it is desired to shut off the full light, the key G is turned inthe usual manner by bringing the stop G2 on the key in contact with thestop G2 of the lower shell F, this shuts olf the flow of gas through theconduit P in the key. The gas now Iiows around the circumferentialgroove P2, finding its way to the tip through the same passages asbefore, thus providing a small flame for relighting or other uses. Thevolume of gas admitted IOO to the burner is regulated by screwing thetipholder B, B2 in or out of the upper shell, bringing the lower end of thescrew B2 nearer to the concave upper end of the detiector l-I, andthereby reducing the size of the passage through which the gas can pass.The locknut D is provided to secure the adjustment of the tip holderwhere desired and to prevent the escape of gas between the threads, thescrew threads being pulled tightly together. When it is desired to use aflame protector. The key may be operated by a lever secured to it andthe lever may be operated by chains or cords vO, O2, as shown. y

I have shown the device for regulating the volume of gas to be the tipholder, but it is manifest that a device, separate and indeset forth.
